    OpenMP: Fix 'omp declare target' handling for vars [PR99509]

    For variables with 'declare target' attribute,
    varpool_node::get_create marks variables as offload; however,
    if the node already exists, it is not updated. C/C++ may tag
    decl with 'declare target implicit', which may only be after
    varpool creation turned into 'declare target' or 'declare target link';
    in this case, the tagging has to happen in the FE.

    gcc/c/ChangeLog:

            PR c++/99509
            * c-decl.c (finish_decl): For 'omp declare target implicit' vars,
            ensure that the varpool node is marked as offloadable.

    gcc/cp/ChangeLog:

            ensure that the varpool node is marked as offloadable.
